Sass Color Functions
We have divided the color functions in Sass into three parts: Set color functions, Get color functions, and Manipulate color functions:
Sass Set Color Functions
| Function | Description & Example |
|---|---|
| rgb(red, green, blue) | Sets a color using the Red-Green-Blue (RGB) model. An RGB color value is specified with: rgb(red, green, blue). Each parameter defines the intensity of that color and can be an integer between 0 and 255, or a percentage value (from 0% to 100%).
Example: |
| rgba(red, green, blue, alpha) | Sets a color using the Red-Green-Blue-Alpha (RGBA) model. RGBA color values are an extension of RGB color values with an alpha channel – which specifies the opacity of the color. The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
Example: |
| hsl(hue, saturation, lightness) | Sets a color using the Hue-Saturation-Lightness (HSL) model – and represents a cylindrical-coordinate representation of colors. Hue is a degree on the color wheel (from 0 to 360) – 0 or 360 is red, 120 is green, 240 is blue. Saturation is a percentage value; 0% means a shade of gray and 100% is the full color. Lightness is also a percentage; 0% is black, 100% is white.
Example: |
| hsla(hue, saturation, lightness, alpha) | Sets a color using the Hue-Saturation-Lightness-Alpha (HSLA) model. HSLA color values are an extension of HSL color values with an alpha channel – which specifies the opacity of the color. The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).
Example: |
| grayscale(color) | Sets a gray color with the same lightness as color.
Example: |
| complement(color) | Sets a color that is the complementary color of color.
Example: |
| invert(color, weight) | Sets a color that is the inverse or negative color of color. The weight parameter is optional and must be a number between 0% and 100%. Default is 100%.

Sass Get Color Functions
| Function | Description & Example |
|---|---|
| red(color) | Returns the red value of color as a number between 0 and 255.
Example: |
| green(color) | Returns the green value of color as a number between 0 and 255.
Example: |
| blue(color) | Returns the blue value of color as a number between 0 and 255.
Example: |
| hue(color) | Returns the hue of color as a number between 0deg and 360deg.
Example: |
| saturation(color) | Returns the HSL saturation of color as a number between 0% and 100%.
Example: |
| lightness(color) | Returns the HSL lightness of color as a number between 0% and 100%.
Example: |
| alpha(color) | Returns the alpha channel of color as a number between 0 and 1.
Example: |
| opacity(color) | Returns the alpha channel of color as a number between 0 and 1.
Example: |
Sass Manipulate Color Functions
| Function | Description & Example |
|---|---|
| mix(color1, color2, weight) | Creates a color that is a mix of color1 and color2. The weight parameter must be between 0% and 100%. A larger weight means that more of color1 should be used. A smaller weight means that more of color2 should be used. Default is 50%. |
| adjust-hue(color, degrees) | Adjusts the color‘s hue with a degree from -360deg to 360deg.
Example: |
| adjust-color(color, red, green, blue, hue, saturation, lightness, alpha) | Adjusts one or more parameters by the specified amount. This function adds or subtracts the specified amount to/from the existing color value.
Example: |
| change-color(color, red, green, blue, hue, saturation, lightness, alpha) | Sets one or more parameters of a color to new values.
Example: |
| scale-color(color, red, green, blue, saturation, lightness, alpha) | Scales one or more parameters of color. |
| rgba(color, alpha) | Creates a new color of color with the given alpha channel.
Example: |
| lighten(color, amount) | Creates a lighter color of color with an amount between 0% and 100%. The amount parameter increases the HSL lightness by that percent. |
| darken(color, amount) | Creates a darker color of color with an amount between 0% and 100%. The amount parameter decreases the HSL lightness by that percent. |
| saturate(color, amount) | Creates a more saturated color of color with an amount between 0% and 100%. The amount parameter increases the HSL saturation by that percent. |
| desaturate(color, amount) | Creates a less saturated color of color with an amount between 0% and 100%. The amount parameter decreases the HSL saturation by that percent. |
| opacify(color, amount) | Creates a more opaque color of color with an amount between 0 and 1. The amount parameter increases the alpha channel by that amount. |
| fade-in(color, amount) | Creates a more opaque color of color with an amount between 0 and 1. The amount parameter increases the alpha channel by that amount. |
| transparentize(color, amount) | Creates a more transparent color of color with an amount between 0 and 1. The amount parameter decreases the alpha channel by that amount. |
| fade-out(color, amount) | Creates a more transparent color of color with an amount between 0 and 1. The amount parameter decreases the alpha channel by that amount. |
